HAY-STAG KER.

SPECIFICATION formingpart of Letters Patent No. 686,453, dated November12, 1901.

Application filed February 19, 1901. Serial No. 47,947. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, JAMES F. HAZEL, a citizen of the United States ofAmerica, residing at Carrollton, in the county of Carroll and State ofMissouri, have invented certain new and useful Improvements inHay-Stackers; and I do hereby declare that the following is a full,clear, and exact description of the invention,- such as will enableothers to make and use the same, reference being had to the accompanyingdrawings, forming, a part of this specification.

The objects of my invention, primarily, are the reduction of the powerordinarily required to elevate the fork-supporting bars; second, toshorten the fulcrum between the fork-supporting bars and the point atwhich the power is applied to raise the bars in a Vertical position,and, third,to adjust the position of the hay-dumping fork.

The invention consists in the novel construction and combination ofparts such as will be first fully described, and specifically pointedout in the claims.

In the drawings, Figure 1 is a view in perspective of the improvedhay-stacker,showing the fork-bars in a horizontal position to receivethe hay to be stacked, also showing in dotted lines the position of theparts of the haystacker when the hay-fork is raised a portion of thedistance from a horizontal to a vertical position. Fig. 2 is a view inperspective of the hay-stacker,showin g the hay-fork in a verticalposition and also the relative position of the elevating devices. Fig. 3is a detail view, enlarged, of the adjustable support for the haydumpingfork.

Similar letters of reference indicate corresponding parts in all thefigures of the drawand with the rear ends of said bars a a is connectedrigidly the ends of a transverse beam a With the upper edge of the beamsa a, at a point upon said beams about one-fourth the distance from thepoint of connection of the transverse beam (1, with said beam toward thepoint of connection of the transverse beam a are connected therespective ends of the transverse beam a With the outer side portion ofthe beams a a, a slight distance in the rear of the vertical plane ofthe rear edge of the extended ends of the forward beam a are pivotallyconnected, by the pivots b b", the lower ends of the fork-elevatingframe B, consisting of longitudinal bars I) b, the movable ends b b ofwhich bars -when in a normally horizontal position extend a considerabledistance beyond the rear ends of the beams a.

With the upper edges and outer end portions 17 b of thevibrating bars I)b is connected rigidly a transverse bar 0, the ends of which bar extenda short distance beyond the plane of the outer sides of said bars. Withthe upper edges of said bars I) b a short distance in front of the bar 0and toward the pivotal ends of bars I) b is 'rigidly connected aseparate bar D, which is of the same length as bar 0. With the underside portions of the separate bars 0 D at their outer ends are connectedthe lower ends of the fork-teeth c c, the outer ends of which teethextend a considerable distance from the transverse bar 0 and in the samelongitudinal direction as the bars I) b. A series of teeth 0 areconnected with the under side of the transverse bars C D and whichextend in parallel planes with each other and the teeth at the ends ofsaid bars 0 D. With the sides of each forktooth care pivotally connectedby a pivot e the lower ends of an adjustable fork-tooth e, the upperends of which series of fork-teeth extend upwardly at an angle to theseries of fork-teeth c. The adjustable teeth 0 are connectedtransversely by a transverse bar E at a point a short distance from thepivoted lower ends of said teeth, so that the series of teeth are movedin unison with each other.

With the outer side of the fork-elevating bars I) b, a short distancefrom the transverse bar D in the direction of the-pivoted end of saidbars, are connected the teeth-adjusting bars F, in the lower ends ofwhich bars are the longitudinal slots f. Through the bars I) I) extendthe adjusting screw-bolts f, which extend through the slots f, and uponsaid bolts are the adjusting-nuts f The upper ends of the bars F F arepivotally connected atj with the sides of the teeth 6' e adjacent to thebars B B at a point a short distance above the transverse bar E,connecting the series of bars e e.

G represents the elevating reach-bar for the elevation of the framecarrying the hayforks, the lower end of which bar is pivotally connectedwith the upper side of the transverse beam a at a point intermediate theends of said beam, said lower end, to prevent rotation, being arrangedbetween the upright lugs h it upon the base-plate h, which plate issecured to the beam at. Through the lugs h h and bar G extends thepivot-bolt h The length of the elevatingbar G is such that the upper endwhen oscillated forwardly and downwardly in the arc of a circle willextend a short distance beyond the pivoted lower ends of bars I) b andalso a short distance forwardly of a vertical line extending upwardlyfrom the forward ends of beams a a, so as to obtain the advantage of adownpull upon the transverse bar D upon the bars I) b in advance of thevertical line described. With the bars b b and with the sides and upperend of bar G are connected the bracket-arms g g, which extend at rightangles to the said bar and a short distance forwardly from said bar.Between the outer ends of the bracket-arms is a pulley g, which turnsupon a pivot 9 extending through said arms 9 g. With the outer ends ofthe pivot g, which extend beyond the outer sides of the arms g g, arepivotally connected the ends of a clevis g.

In order to support the elevating-bar G laterally, a guide-frame I isprovided, which consists of separate guide-bars it, which are obliquelyinclined at their lower ends and said ends rigidly connected with theupper side of the forward transverse beam 0, and arranged in a parallelposition a short distance apart. The upper ends of the bars i 7; extendrearwardly and upwardly at an angle to the beam at to a position on eachside of the elevating-bar G in a vertical line extended upwardly fromthe beam afiand with the outer side portion of said ends are connectedrigidly the upper ends of the standards 2' 91 the lower ends of whichstandards are inclined outwardly at an angle to said guide-bars t i andconnected rigidly with the inner sides of bars b b and are connectedwith eyebolts g g, which bolts are secured to the upper side of bar Dand arranged a short distance apart from each other and form the pointof connection of said bar with the bars B B.

L represents an iron weight for imparting the initial rearward movementof the hayforks and bars I) b when in a vertical position and is placedupon the ground in advance of the transverse beam a and in which weightis an eyebolt Z. Said weight is connected with a rope M, in which at apoint intermediate the ends of said rope is formed a loop which extendsaround the transverse beam a and thence through the eyebolt Z in weightL and a night made in said rope to the said eye. Thence the ends m m ofsaid rope (which are of the proper length to permit of the raising ofthe bars b b to a vertical position) are connected with the eyebolts m mon the u pper side of the transverse bar D.

The tackle for hoisting the bars I) b consists of a pulley n, arrangedin position between the lower ends of the guide-bars i 2', near the beamat and upon the pivotn. Upon the beam a is a pulley O, which is securedto said beam by a strap 0, connected with the forward edge of said beamopposite the pulley n. With the clevis g on the upper end of theelevating-bar G is connected one end of a hoisting-rope P, the other endof which rope is extended over the pulley n and is thence extended overthe pulley g at the upper end of said bar G, thence extended over thepulley O on beam a and with the free end of said rope is connected adraft-animal or such other power as is convenient to operate thehay-stacker.

With the outer side of the bars I) b, a suitable distance below theupper ends of said bars, is connected one end of the brace-bars b 12 theupper ends of said bars being inclined outwardly and connected with theouter ends of the transverse bar 0 at the upper end of bars I) b.

The position of the various parts of the hay-stacker being as shown infull lines in Fig. 1 and with the fork-teeth c horizontally extendedupon the ground, the hay to be stacked is placed in the desired quantityupon said teeth, the load being also retarded from falling forward bythe teeth e. Power being applied to the hoisting-rope P, which istransmitted through ropes g g to the upper end of the bars I) b and thehay fork or teeth 0 and e, the upper end of the reach-bar G is readilymoved forwardly from its normal vertical position toward beam a*,between the guide-barsz' i of the guide-frame I, and downwardly towardthe beam (1 taking up the slack in the ends m m of the rope M andraising the movable ends of bars b b to a vertical position andelevating the load of hay to be stacked. In the movement upwardly of themovable ends of bars I) b the hay upon the teeth 0 shifts its position,and the weight is transferred to the teeth e and carried by IIC .construction.

said teeth to the vertical position described of the barsb b when thehay is dumped upon the ground, and the operation of the stacker repeateduntil the successive deposits form a stack of the requisite height. Incompleting the upper and forward movement described, the tension uponthe ends m m of rope M raises the weight L from the ground and sustainsit in an elevated position. At the same time the tackle-rope P draws theupper end of the reach-bar Gr to a position a short dis tance above thepulley O, and as the end of the bar Gtakes a position forward of thepivoted ends of bars-b b the angle of the rope P gives the'forwardimpetus to the upper ends of bars I) 'b, and the said bars are raised toa vertical position, and the lower ends of the bars 12 I) contact withbeam a as seen in Fig. 2, and while the power is retained upon the endof bar G the vertical position of the bars is maintained. Upon releasingthe power upon the hoisting-tackle the weight L causes the firstbackward movement of the upper ends of the bars 1) b, and as the weightreaches the ground the rearward inclination of the bars is sufficientfrom their own weight and the forks c c to cause the bars to move towardthe ground as the tackle pays out the rope P and the fork-teeth 0 takethe position as seen in Fig. l in readiness for the deposit of its loadof hay or other material. Upon releasing the nuts on the bolts f theadjusting-bar F is then operated to change the angle of the series ofteeth 6' at any desired angle of inclination to the teeth 0, so thatwhen the bars I) b are in a vertical position the discharge of the loadof hay is effected with great or less speed, as the movable condition ofthe material may require.

In my invention I obtain a large per cent. of effective work with adecrease in the weightof the stacker from its simplicity of It isobvious that the guiding of the bar G may be effected from the beam at,and its lateral movement counteracted by the upward extension of lugs hh, and such other modifications employed as are within the scope of theinvention.

1 am aware that pivoted frames of various kinds have been employedto'raise the forkelevating frame, the objection to which is in theirweight, which has to be overcome before the power is transmitted to thefork-ele-. vating frame. In my invention the fork-elevating bar iscomposed of light material,

which enables the raising of the fork-elevating frame with theapplication of less power than in ordinary stackers.

Having fully described my invention, what I now claim as new, and desireto secure by Letters Patent, is

1. In a stacker the combination, with the base-frame, of afork-elevating frame pivotally connected with the forward end thereof,stationary guide-bars arranged in a parallel position and having theirforward ends rigidly connected with the forward end of the base-frameand their rear ends extending upwardlyat an angle to the base-frame,standards connected at their upper ends with the rear ends of saidguide-bars, and with the base-frame at their lower ends, an elevatingbarpivotallyconnected with the base-frame at its lower end and movable inthe arc of a circle between said stationary guide-bars, hoisting devicesconnected with the upper end of the elevating-bar and the fork-elevating frame, and hoisting-tackle connected with the elevating-bar and withthe forward end of the base-frame.
